fishing and diving for coral.

In the second half of the last century, Carloforte had gone through an enormous development, encouraged by the mining of minerals near the Iglesiente-Guspinese area. These minerals were transported to the island by entrpreneurs and the local workforce, to be later shipped to far-off destinations.
With the mining crisis, came a strong revival of the traditional activities
(fishing, craftsman ship).
